OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

Corneal lenticule allotransplant

This animal study looked at corneal lenticule allograft transplantation in rabbits. Seven rabbits underwent small incision lenticule extraction (SMILE) procedures, where their stromal lenticules were extracted and transplanted fresh into pre-prepared corneal stromal pockets of seven recipient eyes. Animals were...

Retinal ganglion cell loss in diabetes and diabetic retinopathy

The aim of this observational case control study was to evaluate the association of diabetes and diabetic retinopathy (DR) with retinal ganglion cell loss. Cases were Chinese patients with type 2 diabetes with and without DR, aged 40-80 years. Eligible...

Using OCT to screen and monitor Alzheimer’s disease

Alzheimer’s disease (AD) is a neurodegenerative illness characterised by progressive decline in cognitive function. AD is the main cause of dementia worldwide. Over recent years researchers have strived to find biomarkers to diagnose AD, particularly in the early stages of...

High myopia macular thickness

The purpose of this study was to compare macular thickness and volume in 15 highly myopic (>-6D) young children with 11 age-matched controls (-2 to +4D refractive errors) using Stratus third generation OCT. Mean spherical equivalent was -9.42 ±2.81D for...

Amblyopic choroidal thickness

The authors studied choroidal thickness in 38 paediatric cases (76 eyes) with unilateral amblyopia to evaluate the differences between amblyopic and fellow eyes, and compare them with 19 healthy control subjects (38 eyes). Anisometropic amblyopia was present in 17 cases...

Lucentis for pseudophakic CMO

Pseudophakic cystoid macular oedema (CMO) develops angiographically in up to 20-30% after uneventful phacoemulsification. This study aimed to evaluate the potential efficacy and safety of intravitreal ranibizumab in patients with pseudophakic CMO after cataract surgery. Seven eyes were included in...

Choroidal defects in neurofibromatosis

The aim of this study was to investigate the frequency of choroidal abnormalities using infrared reflectance imaging with optical coherence tomography (OCT) in paediatric patients with neurofibromatosis (NF) type 1. Thirty-eight eyes of 19 patients were reviewed. NF1 was diagnosed...

Gender and ethnicity related differences in optic nerve head

The authors investigated the effect of ethnicity and gender on optic nerve head morphology comparing Indian and Caucasian males and females. The optic nerve head was investigated using spectral-domain optic coherence tomography (SD-OCT). Results showed that disc and rim areas...

Choroidal thickness in ocular sarcoidosis by OCT measurement

This is the first study to evaluate the choroidal thickness in patients with ocular sarcoidosis during the quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing with normal subjects. Ocular sarcoidosis may affect the choroidal circulation (occlusive...

The prevalence of macular cysts in patients with clinical cone-rod dystrophy determined by spectral domain optical coherence tomography

Cone-rod dystrophy is a progressive photoreceptor disorder which has multiple inheritance patterns. It is rare, with a prevalence of 1 in 40,000. Macular cysts are well recognised in other photoreceptor conditions such as retinitis pigments and choroideraemia, while they are...

SLT short-term results

The aim of the study was to evaluate the risk of adverse effects and short-term results after 360 degrees selective laser trabeculoplasty (SLT) in glaucoma patients. The authors enrolled 64 eyes of 64 patients all who had poorly controlled primary...
